With still no sign of 52 year old Jeffrey Boucher, Durham Regional Police announced on Thursday, that they plan to start scaling back the search for the missing high school teacher.
Sgt Nancy Van Rooy with Durham Regional Police say they are holding onto hope that Boucher is inside somewhere, out of the elements.
He was reported missing at around 8:30 on Monday morning, when he left his Whitby home for a jog.
Authorities have also appealed to anyone who may have been in contact with Boucher, to come forward.
Van Rooy says at this point, there's no evidence of an electronic footprint left behind by Boucher.
That means, they haven't seen any indication he's made bank transactions, or logged onto a computer using his old password.
Police say they are scaling back the search, because they are confident they've been able to cover, by ground and by air, all the areas known to him.
While they are scaling back one aspect of the search, they are extending it into other municipalities, and involving other police services.
Meanwhile, revelations on Wednesday, that money had been found in Boucher's desk at Bowmanville High School, where he was a teacher, have been put to rest.
A source had told Newstalk1010 that an investigation had been launched late last week, when an 'unusually large' sum of money had been discovered.
The Director of Education at the Kawartha Pine Ridge District School Board says they are aware of the money and had spoken to Boucher about it.
Turns out, the 35 hundred dollars was collected for an upcoming ski trip.
It's also been uncovered, that Boucher was unaccounted for on Sunday night as well.
His 17 year old daughter tweeted this on Sunday:
When asked about it, Bettina Boucher told reporters 'it was irrelevant'.
Police are canvassing areas near Boucher's home in Whitby. He usually runs about 10 km a day, but doesn't have a regular running route.
A command post has been set up on Whitburn Street in Whitby, which is near the man's home.
Boucher is described as a white man, 6’ tall, 180 lbs. with grey and white short hair.
Nancy Van Rooy from Durham Regional Police says police do not believe the disappearance is suspicious or that any foul play is involved. But she says there have been very few leads.
Once again using Twitter, his daughter Bettina expressed her concern.
Boucher did not arrive for work on Monday and police say his vehicle and other personal items were found at his home. Van Rooy said it's also known that Boucher did not have his cellphone with him.
Boucher's mother, Mary, spoke with Newstalk1010's Jim Richards.
Police have been searching the man's Whitby neighbourhood as well as a nearby conservation area and other parks and trails in the vicinity.
Anyone with new information regarding the whereabouts of the missing male or who may have had contact with him recently is asked to Central West Division at 1-888-579-1520.
